Pulling Chestnut seedlings to be used for grafting

On March 4, 2022 Caleb Kell, who works on chestnut breeding at Purdue’s Hardwood Tree Improvement and Regeneration Center, pulled and packaged American chestnut seedlings at the Indiana DNR state tree nursery at Vallonia Indiana. These robust seedlings are one year old. Caleb was assisted by chapter volunteer Sharon Kotnik as well as workers from the nursery.

Many of these seedlings will be used as rootstock. The stem will be cut off a short way above the roots and scion wood will be grafted onto the rootstock. Scion wood is a shoot or twig cut from the upper branches of an existing full grown tree, in this case a long term surviving American chestnut tree.

Often grafting is the only way an old chestnut found in the forest can be preserved. Chestnut trees that are still alive after many years of growing in the wild and surviving the blight are a very valuable genetic resource and their genetics or “germplasm” needs to be preserved for breeding ever more blight resistant chestnuts. The grafted trees are grown in our germplasm conservation orchard, GCO. The pollen and nuts from our GCOs are used to breed new backcross chestnuts and also sent to locations where TACF is doing research on producing transgenic chestnut trees using the oxalate oxidase gene.

Why don't they make a weevil that can't have babies? And put them in the wild? So it'll past it to overs so they'll die out!!!

Planting season is here! This week we planted around 140 genomically selected chestnut seedlings at Meadowview's Duncan Farm for seed orchard production. In 5–7 years, this new seed orchard will be used for breeding and collecting open-pollinated seeds to continually improve disease resistance among our trees. Exciting roots for the future!

out of five trees, I have only one that has survived. Two due to cold killing the tops (16-21 degrees) and two I think killed by squirrels or gophers.

I wrote to you recently and we have one out here in Oregon City OR. In the middle of our woods we just logged. It was planted about 1890. We are mailing out a sample today for you.

Awesome!! 🥰

Approximately how tall are the trees?

🤞
